One of the largest motor omnibus companies in the world was induced to consider the possibilities of this issue, and finally was induced to make the experiment. The “Iwel” plant in question was designed to turn out 6 tons of clean dry rags per week. This may seem to be an enormous quantity to accumulate during a period of seven days, but it must be pointed out that the company in question maintains 2,000 to 3,000 public vehicles upon the roads, as well as several garages and repair shops. The first three months’ experience served to bring home the economic advantages accruing from the scientific exploitation of this form of waste. During this brief period the company reclaimed 67 tons of rags for further use, the value of which at the time was set down at £1,007 7s. 1d.--over $5,000--while from this waste 4,080 gallons of oil, valued at £59 10s.--$297.50--were recovered. Here was a distinct gross saving of £1,066 17s. 1d.--$5,334--which figure was increased to £1,489 15s. 7d.--$7,449--on the credit side by the delivery of new rags to depots valued at £419 12s. 6d.--$2,098--and the sale of small rags unsuited to further work for £3 6s.--$16.50. On the debit side the heaviest expenses were incurred in connection with the purchase of new rags, valued at £405 12s. 9d.--$2,028, cartage of the waste £152 17s. 10d.--$764.44, wages and salaries £157 15s. 1d.--$788.74, and coal £105 0s. 11d.--$525.22. The total outgoings amounted to £1,038 16s. 7d.--$5,194.14, which left a balance of £450 19s.--$2,254.72--actual saving recorded by the treatment of the waste. So far as the reclaimed oil was concerned, while this was unsuited to further utilization in its original province, it was found to form an excellent fuel for the operation of the Diesel engines, and consequently reduced the fuel bill on this account by a corresponding amount.
